How do you usually invoke the C++ compiler? `/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++` not your standard compiler?

Mhh, then `mpicxx` does something that fixes it. You're using MPICH right? Can you post what `mpicxx -compile_info` prints out?

Ahh, so mpich picked up `clang++` instead of the Xcode `c++`. Can you try to rebuild DASH with the following? ``` $ CC=clang CXX=clang++ bash build.sh ``` That should tell...

AFAICS, your C++ compiler installation is broken as the compiler is unable to compile a simple C++ application by itself. For some weird reason MPICH seems to correct for this...

This has been addressed in #677 (pending review) :)

The offsets are still broken and I cannot seem to figure out which offsets to use. Will look at it again tomorrow... Any help is appreciated, though.

@fuchsto I'm giving up here as it is not clear to me anymore which are global and local block coordinates and indexes. Also, I suspect that there are fixes lingering...

What is the way forward here? I don't remember this was discussed at the F2F but it keep biting...

Can the `RegionSpec` be implemented in terms of `Dimensional`?
